Coffiq | AI-Powered Coffee Tracker React Native App

Coffiq is a production-ready, AI-powered multi-application platform built to simplify daily caffeine tracking, sleep health optimization, merchant loyalty reward redemptions, and system administration. The platform comprises a centralized Node.js REST API with real-time WebSockets and two high-performance React Native CLI mobile apps built with TypeScript, Redux Toolkit, NativeWind v5 (Tailwind CSS), and smooth UI animations.

AI-Assisted Development: In accordance with Envato’s AI disclosure policy, the author discloses that portions of this product’s codebase were developed with the assistance of AI coding tools (Google Gemini). All generated code has been thoroughly reviewed, tested, debugged, and validated by the author to ensure production quality and correctness.

Runtime AI Features: This application also integrates AI services (Google Gemini and Groq Cloud) as runtime features for end-users. These are application features, not development tools — see the detailed disclosure below.

Stripe Billing Engine: The complete source code for the Stripe payment integration, subscription management, and billing engine is included in the package. Buyers receive full control over all payment features under the Regular license with no external dependencies beyond the Stripe SDK.

⚠️ AI Features & API Usage Disclosure

In accordance with Envato’s item quality and disclosure requirements, please be advised that this application leverages Artificial Intelligence to power specific core features. An active API key from Groq Cloud and/or Google is required to utilize these AI functionalities.

• AI Service Providers & Models: Groq Cloud (openai/gpt-oss-120b / qwen/qwen3.6-27b) and Google Gemini (gemini-2.5-flash).
• AI Beverage & Label Scanner: Uses Google Gemini Vision models to analyze captured cup photos or nutrition label scans, automatically identifying the drink and estimating volume and caffeine.
• AI Coffee & Sleep Coach Chat: Interactive conversational assistant to advise users on bedtime schedules, caffeine half-life calculations, and recipes.
• Voice Log Command Interpreter: Uses Groq speech processing to capture spoken audio logs (e.g. “I had a double espresso”) and convert them into drink logs.

Security Note: All AI requests route securely through the Node.js backend. API keys are strictly managed via the backend .env file or dynamically via the System Settings table. They are never exposed to client devices.
